Green sulfur bacteria
WebGreen sulfur bacteria contain chlorosomes, organelles that are so efficient at harvesting light that green sulfur bacteria can grow at much lower light intensities than other light … WebThe electron transport chain of green sulfur bacteria — such as is present in the model organism Chlorobaculum tepidum — uses the reaction center bacteriochlorophyll pair, P840. When light is absorbed by the reaction center, P840 enters an excited state with a large negative reduction potential, and so readily donates the electron to ...
